Molybdenum tube

Molybdenum alloy, is based on molybdenum substrate to join other elements, constitute the non-ferrous alloy. Main alloy elements are titanium, zirconium, hafnium, tungsten and rare earth elements. Titanium, zirconium, hafnium elements not only have solid solution strengthening effect on molybdenum alloy, keep low temperature plastic alloy, but also can form stable, diffuse distribution of carbide phase, improve the strength of the alloy and the recrystallization temperature. Molybdenum alloy with good thermal conductivity, electrical conductivity and low expansion coefficient, at high temperatures ( 1100～1650℃) With high intensity, easier than tungsten processing. Can be used as a valve gate and anode, electric light source of the support material, and used to make die casting and extrusion mould, aircraft parts, etc. Because of molybdenum alloy has a low temperature brittleness and welding brittleness, and high temperature oxidation, so its development was restricted. Industrial production of molybdenum alloys have molybdenum titanium zirconium, molybdenum, tungsten and molybdenum alloy, rare earth application is more * * class. Molybdenum alloy is the main way of strengthening, solid solution strengthening, precipitation strengthening and work hardening
